In recent years, attention has been paid to the development of dairy cow production. Farmers' milk raising bulls have become an important way to get rich. However, because many cattle farmers do not pay attention to raising good milk bull calves and do not pay attention to the application of the scientific development of fat bull calves, so cattle breeding Economic efficiency is not high. In order to increase the economic benefits of milking bull calves, the experience of the demonstration model village of fast fattening dairy bulls has been introduced as follows for reference by farmers.

After investigation and research, the majority of black-and-white cows in the world have been sterilized except for seed use. Black-and-white cows have high conversion rates to feed, fast growth, and lean meat. In recent years, there have been many demonstration cattle breeding households raising black-and-white flowers and hybrid male yak. ​​Each raising of 1-1.5 years can generally benefit from 400-500 yuan. With 100 kilograms of milk and a certain amount of milk replacer, the live weight can reach 350 kilograms at one year old and 450-500 kilograms at one year and a half. Some demonstration village farmers fed sawdust mixture for 5-9 months of calf, showing high digestibility, small fecal odor, not easy to get gastrointestinal diseases, beef white fat after slaughter, meat taste thin.
The formula of the mixture is: 3 kg of corn flour, 1.15 kg of bran, 0.75 kg of bean cake or sunflower cake, 0.05 kg of bone meal and salt, and 2.3 kg of sawdust. Sawdust accounts for 31.5% of the total mix, mainly poplar sawdust.
Farmers need to be aware that if the slaughter is to be kept for one year, bull calves can't go. Breeding practices have proven that while castration is good for weight gain, it can affect weight gain for a period of time after surgery. If the farmers are ready to raise to the age of one and a half or even two years old, they must turn their backs. Castration can be performed at the age of one year or one year old. Breeding practice has proven that the best season for castration is spring. Most of the improved cattle are castrated at the age of 1 year.
